Let's divide 90269218 by 255
Our goal is to divide 90269218 by 255.

Advancing to step 1:
If we divide 9 by 255, we get 0 and a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (0) from the dividend and append it to 9, then repeat: 90 / 255

Moving on to step 2:
The number 255 fits into 90 0 times, leaving a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 90, we end up with 90.
Grab the next digit (2) from the dividend, add it to 90, then carry on: 902 / 255

Advancing to step 3:
The number 255 fits into 902 3 times, leaving a remainder of 137.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 765 from 902 leaves us with 137.
Take the next digit (6) from the dividend and append it to 137, then repeat: 1376 / 255

On to step 4:
When dividing 1376 by 255, we get 5 with a remainder of 101.
Write down 5 as next digit of the result. 
Result so far: 35.0
If we take 1275 away from 1376, we end up with 101.
Append the next digit (9) from the dividend to 101 and continue with: 1019 / 255

Moving on to step 5:
If we divide 1019 by 255, we get 3 and a remainder of 254.
The number 3 becomes the next digit in our result. 
Result so far: 353.0
The remainder is 254 after subtracting 765 from 1019.
Append the next digit (2) from the dividend to 254 and continue with: 2542 / 255

Moving on to step 6:
When dividing 2542 by 255, we get 9 with a remainder of 247.
The number 9 becomes the next digit in our result. 
Result so far: 3539.0
The remainder is 247 after subtracting 2295 from 2542.
Append the next digit (1) from the dividend to 247 and continue with: 2471 / 255

Let's proceed to step 7:
2471 divided by 255 is 9 with a remainder of 176.
The number 9 becomes the next digit in our result. 
Result so far: 35399.0
Subtract 2295 from 2471 to get 176.
Take the next digit (8) from the dividend and append it to 176, then repeat: 1768 / 255

On to step 8:
The number 255 fits into 1768 6 times, leaving a remainder of 238.
Record the quotient 6 as the next digit in the result. 
Result so far: 353996.0
Subtracting 1530 from 1768 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Step 9:
If we divide 2380 by 255, we get 9 and a remainder of 85.
Record the quotient 9 as the next digit in the result. 
Result so far: 353996.9
The remainder is 85 after subtracting 2295 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
The number 255 fits into 850 3 times, leaving a remainder of 85.
Use 3 as the next digit of our solution. 
Result so far: 353996.93
If we take 765 away from 850, we end up with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
When dividing 850 by 255, we get 3 with a remainder of 85.
Record the quotient 3 as the next digit in the result. 
Result so far: 353996.933
Subtracting 765 from 850 leaves us with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

After the division, we end up with 353996.933 and a remainder of 0.0085.
